Many people experience headaches on the right side of their head only. The pain may be accompanied by other symptoms, including fatigue, nausea, and visual disturbances.

Almost 50 percent of adults each year report headaches, making them among the most common health complaints.

Read on to learn more about headaches on the right side of the head and remedies to help manage the pain.

A headache on the right side of the head may be caused by:

Neurological issues

Neurological issues can cause a headache on the right side only.

Various issues in the brain can cause a one-sided pain.

The following neurological conditions may be responsible for headaches on one side:

Occipital neuralgia: This occurs when nerves running from the top of the spinal cord to the scalp (occipital nerves) become damaged or inflamed. Symptoms include sharp pain in the back of the head and neck, pain behind the eye, and sensitivity to light.
Temporal arteritis: Arteries in the head and neck become inflamed with temporal arteritis. Along with muscle pain, it causes a severe headache on the side of the head. Other symptoms include fatigue, jaw pain, and tender temples.
Trigeminal neuralgia: This causes intense pain in the face and head. The pain usually affects only one side at a time. It is caused by disruption to the trigeminal nerve at the base of the brain.
Medication use

Headaches can occur as a side effect of prescription or over-the-counter (OTC) medications. They can also be caused by overusing medication, including OTC painkillers such as:

acetaminophen (Tylenol)
ibuprofen (Motrin, Advil)
This type of headache is called a rebound headache. According to the World Health Organization, it is the most common type of secondary headache disorder. A secondary headache is a headache that is caused by another condition.

Headaches caused by medication overuse are often at their worst upon waking.

Other causes

Other causes of headaches can lead to pain across the entire head or just one side.

These include:

an aneurysm, a weak or bulging artery wall
head injury
infections, including sinus infections
fluctuations in blood sugar levels caused by missing meals
muscle strains or knots in the neck
What types of headache affect the right side?
There are over 300 types of headache, about 90 percent of which have no known cause.

However, a migraine or a cluster headache are the most likely causes of a headache on the right side of the head. Tension headaches may also cause pain on one side in some people.


Migraines are often accompanied by sensitivity to light and sound.

Genetics are thought to play a role in migraine headaches — a type of severe headache that causes a pulsating sensation or throbbing pain in the head.

The severe pulsating sensations or throbbing are usually accompanied by:

blurred vision
sensitivity to light
sensitivity to sound
Up to a third of people that get migraines experience visual disturbances or temporary loss of vision (known as an aura) before the onset of the pain. Symptoms can last for up to 72 hours if untreated, with the pain typically affecting only one side of the head.

The following factors can trigger migraines:

bright lights
changes in weather (humidity, heat, pressure)
emotional stress or anxiety
foods and drinks, such as alcohol, chocolate, cheese, and cured meats
hormonal changes in women
loud noises
skipping meals
strong smells
too much or too little sleep
Early treatment is key to reducing the length and severity of symptoms. Treatments include OTC or prescription medicines. Prevention involves avoiding triggers and using preventative medications, in some cases.

Cluster headaches

Cluster headaches are rare but severe headaches that occur in cyclical patterns. The pain is intense and usually located around one eye. It may also radiate to other areas of the head and face, as well as the neck and shoulders.

People typically experience frequent headache attacks (clusters) for weeks or months before a period of remission.

Other symptoms of cluster headaches include:

facial sweating
pale or flushed skin
red or watery eyes
stuffy or runny nose
swelling around the affected eye
Men tend to experience cluster headaches more often than women. The exact cause is unknown, but smoking, alcohol use, and a family history of cluster headaches may increase risk.

There is no cure for the condition, although treatments can reduce the number and severity of cluster headaches.

Tension headaches

Tension headaches are the most common type of headache, occurring in 75 percent of people.

They usually affect both sides of the head, but some people may have symptoms on one side only.

Signs include:

dull, aching pain
scalp tenderness
tender or tight shoulder and neck muscles
tightness or pressure across the forehead, sides, or back of the head
Symptoms usually last for a few minutes to a few hours and are mild to moderate in severity.

Occasional tension headaches can be treated with OTC pain relievers or home remedies. People with frequent tension headaches may need to change their lifestyle, identify and avoid triggers, or use prescription medications.

When to see a doctor
Many cases of headache will resolve on their own, without any intervention. People that experience headaches regularly should make an appointment with their doctor to identify the underlying cause.

Anyone who experiences the following symptoms alongside a headache must seek medical attention:

changes in vision
head injury
increased pain during movement
neck stiffness
personality or cognitive changes
sleep disturbances
slurred speech
People who have headaches that are very severe or get progressively worse should also see a doctor.
